Embodiment Construction

[0024] The hardware structure diagram of the embedded image fusion system for video background detection is as follows: figure 1 As shown, the signal of the imaging sensor 1 enters the A / D multi-channel acquisition 3 to convert the analog video signal into a digital pixel value, and after inputting the FPGA device 4 for processing, the video signal is transmitted to the DSP image fusion module 5, and the DSP image fusion module 5 Carry out image fusion according to the sensor type signal sent by the sensor type selection switch 2, and finally send the fused image through the liquid crystal display interface 6 for display.

[0025] Its specific configuration is as follows:

[0026] Two imaging sensors are used, one is AVT industrial CCD camera F-032B / C, and the other is Infrared Solutions can provide a thermal imager based on uncooled bolometer technology: IR-160 imager, which can Output 160×120 pixel NTSC or PAL video output signal; the sensor type selection switch and DSP im...

Abstract

The present invention relates to an embedded image involvement system based on video background detection and a method thereof. The system realizes the acquisition of data on an FPGA and a multiresolution method reduces or eliminates noise brought about by an imaging sensor, transmits a video image signal to a DSP system according to a specific clock. Image fusion technology based on video background detection on a DSP1 platform is used for fusing a video image; the image infusion technology adopted by a DSP is arranged at a category option switch of the sensor so as to increase the applicable scope of the system. The system is a key link in the field of the information fusion, the embedded system development and can be very flexibly applied in systems of optical imaging, target surveillance, security check and the like. The invention has the advantages of wide applicable scope, high infusion precision, etc.

Description

technical field [0001] The invention relates to an image fusion method, in particular to an embedded image fusion method based on video background detection. Background technique [0002] Image fusion technology is the fusion of visual information in multi-sensor information fusion. It uses different imaging methods of various imaging sensors to provide complementary information for different images, increase the amount of image information, reduce the amount of original image data, and improve adaptability to the environment. In order to obtain more reliable and accurate useful information for observation or further processing. Image fusion technology is an emerging technology that integrates sensors, signal processing, image processing and artificial intelligence. In recent years, it has become a very important and useful image analysis and computer vision technology. , robotics, medical image processing, and military applications have broad application prospects.
